FOR IMMEDIATE RELEASE
THERMODYNAMIC CYCLES AND THE NEW FIELD OF TURBONETICS OFFER HOPE FOR THE FUTURE CHICAGO, IL April 1, 2004,--/World-Wire/-- Thomas L. Cosby, an alternate-future energy pioneer, today announced he has patented an alternate-energy automobile engine that offers solution to the energy crisis. To those who have sensed intuitively that there is a better way, here is the answer! "Revised thermodynamic cycles and the new field of "turbonetics" offer hope for the future. The course of world events will be transformed by this unlimited, simple, non-polluting energy source. Hereafter, fossil and nuclear fuels are declared obsolete." said Thomas Cosby, who credits 48 years of concepts and international patents including Patents #5,107,682 and #5,626,459. Other relevant energy patents include an energy cycle that will eliminate all the problems associated with the 1300 coal burning facilities in this country alone that generate "dirty" electricity that were grand fathered in by the US Government decades ago. Additionally, Cosby said: "This revised cycle with only minor alterations and costs to existing plants will make it possible to retrofit these facilities and save up to 70% of the fuel and reduce air pollutants by 70% because that amount of fuel will not have to be burned." A major collateral benefit of this cycle is that it requires little or no cooling water . The Limited Expansion Vapor Cycle Proposal Based in part on U.S. Patents # 4,479,354 & 5,107,682, et.al. Background and summary of the invention and the proposal. The present proposal relates to a method and apparatus modifications for reducing the amount of fuel required to perform work in a steam cycle to generate electricity. The cycle is a modification of the conventional Rankine Cycle. In the Rankine Cycle, fuel is used to heat a vessel containing water to generate pressurized steam. The steam is then usually superheated and passed across a turbine array to power an electric generator, Upon exit from the turbine the exhaust steam is condensed -vapor to liquid, making it economical to return it to the boiler with the least amount of parasitic work. In the cycle, two phase changes occur: once from liquid to vapor and once vapor to liquid The amount of heat needed to make the first transformation is accepted as 950btu/lb, this amount is removed for the reverse. A representative heat content for the high pressure /temperature point is 1368 BTU/LB of which 1320 is added each cycle. of that, 370 is convertible to work! The 950 is then only preparatory and is added/subtracted to make it economical to re-enter the boiler with the smallest volume for the smallest amount of work. Make Sense? The obvious solution is to save that 72%(950/1320) preparatory fuel by devising a way to obviate the phase change. This then is the goal of this proposal. Most turbines used for electricity generation expand the steam to the maximum to extract the maximum amount of heat. This proposed cycle limits the amount of expansion to the point where it is still feasible to compress the steam economically. At some point we pass the economical point of no return, i.e., it is no longer possible to obtain a net work output if work is used to re-compress the large volume of vapor to starting--work in =work out. However, if the expansion is stopped before maximum allowable, or what is currently deemed ideal, and "intra" stage cooling is effected, it is possible to perform the compression process and require a minimum of parasitic work. For example: Compression work can be estimated by dh. If the vapor to be compressed is cooled during the process by 50% dh, then 50% of the work of compression is done without mechanical work. (We anticipate a greater saving) To make the compression feasible, a new type of compressor has been designed to accomplish "isentropic" compression and by counterflow, the cooler vapor entering the compressor cools that being compressed-- an internal heat exchange occurs during the compression process. ( The heat is recycled in the process) CONTACT: Thomas Cosby, 773-731-6040, cozmat@att.net |
